Following her laboratory-based PhD in Virology and Immunology at the University of Cambridge, Dr. Stagg moved to the Health Protection Agency's Tuberculosis Section in 2010 and retrained in epidemiology. After her secondment to Brigham and Women's Hospital/Harvard School of Public Health, in 2012 she took up a Research Associate post at University College London in the group of Professor Ibrahim Abubakar, from which she was promoted to Senior Research Associate in 2013, and thence to Senior Research Fellow. She has broad interests in the epidemiology of communicable diseases across vulnerable and neglected population groups, particularly the interface between between the laboratory sciences and public health, as well as scientifically novel academic research and policy.
